Awesome! One thing that I was wanting to do is to disable the auto off feature of the camera as well as using the A/V output all the time when I am SHOOTING, not just playback. How would I enable these?

For the SX30, the video cable supplied is "AV Cable AVC-DC400ST", which is the same as the sx130is.

In order to use the USB functions (for something like these remote units), as well as see the video output, you need to build (or buy) a USB/Video splitter. I'm sure you can buy one pre-build somewhere, but I built one for myself. A description and pictures are here -> http://www.achillies.com/CHDK_Files/USB_Splitter.htm

*Note: with my camera the only way to clear EVERYTHING from the display while shooting, is to use manual or program mode. Most of the other modes leave a status icon in the top right.

I'm new to CHDK having just installed it on my Canon PowerShot A570is. I'm interested in making a USB remote trigger so that I can use it when digiscoping. Mechanical remote cable releases are, at best, awkward and clumsy and the USB route seems to be the right way to go. Can anyone help?Will appreciate any help and advice.Many thanks

Welcome to CHDK! You have the correct forum if you want to build your own USB remote switch. There are a number of versions in the presious posting of this forum that should work.

I noticed that you are new to CHDK, so I wanted to let you know there are also commercial switch triggers that will work with CHDK as well. Here is a posting on one that I found/use (Ricoh CA-1 cable switch) and I carry it with me all the time because it is so small and light weight: http://chdk.setepontos.com/index.php?topic=4348.msg59492#msg59492

Whether you build your own or buy a commercial one it is simple to use with CHDK afterwards.
